Title: Solid state image pickup apparatus
Inventor: HORII SAKAKI
IPC: H04N5/335
Filed: 1980-05-14
Abstract: PURPOSE: To contrive the prevention of a blooming without narrowing an effective light receiving area by a method wherein a charge transfer elements array for vertical transfer is given two functions of transferring the charge and of sweeping out a overflowed electric charge.  
     CONSTITUTION: Lights incided in the photoelectric conversion elements array generate the electric charges in a substrate and make them be stored. The electric charges generated boyond the amount of the saturated charge are overflowed to the charge transfer elements 2 and induced to a drain region 23 through a selected gate region 24. After pulse are applied to the charge transfer elements array 2 and the electric charges are swept out, signal charges in the photoelectric conversion elements array 1 are fed to the charge transfer elements array 2. The signal charges are further transferred to a storage region 22 and read out in sequence from a read- out register 4.

IPC: F02D41/40
Filed: 1983-04-14
Abstract: PURPOSE:To permit to detect the injection timing accurately by a method wherein vibration in the fuel system of a cylinder, going to inject fuel, is detected at a time one cylinder before the cylinder corresponding to a detecting mark and the injection timing is operated by a delay time at a time whereat an injection initiation detecting output is delayed so that a detecting mark coincides with a mating mark. CONSTITUTION:An injection initiating pulse PA, outputted from an injection initiation detecting circuit 5, is delayed in a delaying circuit 10 to luminate a timing light 12 and adjust an upper dead point mark so as to coincide with the mating mark. In this case, the delay time of the delaying circuit 10 is a time between the upper dead point and the injection initiating time of fourth cylinder of the six-cylinder engine and the fuel injection timing of the fourth cylinder may be obtained by the degree of angle when the delay time is operated in angle and is corrected by 120 deg.. The injection initiating pulse PA is delayed so that the upper dead point mark, which is the detecting mark, coincides with the mating mark, and the delay time is indicated by the degree of angle, whereby the injection timing may be measured correctly.

Filed: 1986-03-24
Abstract: PURPOSE:To perform knocking control in an accurate manner, by installing an optical fiber transmitting light in a combustion chamber and a controlling device which reduces a fuel quantity when output of a cold driving state detecting device is interrupted. CONSTITUTION:An optical fiber 19 transmits light in a combustion chamber 14 to a photodetector 30 as a light signal S1.

Abstract: PURPOSE:To improve the reliability of wedge bonding and to improve working efficiency, by controlling positioning operation based on detected signals from a distance sensor so that the surface of a pellet is always located at a proper bonding height. CONSTITUTION:Automatic bonding is performed by outputting control signals SA, SC, SD and SE at the suitable times based on an image sensing signal SF, which is outputted from an ITV camera 29 and indicates leads on a substrate 31 and the pattern on a pellet 1.

The control part 10 outputs a control signal SB so that a difference L1 between the distance at this time and the normal distance is made to be zero, i.e., the surface of the pellet 1 is lowered by  Ll. A work stage 11 is lowered, and the height is corrected. As a result, the tool 10 becomes vertical with respect to the surface of the pellet 1.

Abstract: PURPOSE:To form the opening section of an insulating film having a taper by conducting dry etching by using a mask having a taper. CONSTITUTION:A SiO2 layer 32 is formed onto a Si substrate 31, and a resist 33 is shaped as a lift-off material. A SiO2 layer 34 is further shaped through plasma CVD, but the layer 34 is formed as shown in (b) when the surface is etched by HF because the speed of etching is faster in a section A through the method. When the resist 33 is remoed, the oxide film 34 is also removed. When the whole surface is etched by RIE, the opening section is widened as shown in (e) with the progress of etching because the taper is formed in the oxide film 34 as the mask while the thickness of the oxide film 34 is also decreased gradually. The opening is formed as shown in (d), and a wiring layer having high reliability free of steo disconnection is shaped when Al 35 is evaporated.

Abstract: PURPOSE:To eliminate the sheathed filter of a TV camera by forming a plurality of types of junction depths as the distance between the photodetecting surface of the photodetector of a silicon substrate and a P-N junction surface, thereby incorporating a spectral sensitivity characteristics responsive to primary color lights. CONSTITUTION:The junction depths of the distances 51-53 between the photodetecting surfaces of the photodetectors 9-11 of a silicon substrate 1 and a P-N junction surface are formed in types having spectral sensitivity characteristics highly sensitive to the respective primary color lights of red, green and blue lights. Since the relative spectral sensitivities are approximately equal, a sheathed filter becomes unncessary. The mixture ratio of the red, green and blue lights can be selected to an arbitrary value by suitably adjusting the junction area of the photodetectors 9- 11 and the silicon substrate 1.
